![]() ![]() floridensis, on exhibition, is also described. 25–24 million years old, and occurs in an interval not well represented in the classic Arikareean sequence of western Nebraska. floridensis is late early Arikareean (Ar2) in age, ca. Based on the associated faunal remains and age determinations, M. Mesoreodon floridensis differs from most other species assigned to this genus in the relative development of the nasal region, possible presence of a facial vacuity, configuration of the preorbital fossa, relatively simple occipital and zygomatic morphology, and imbricated premolar morphology. ![]() ![]() new species, Mesoreodon floridensis, and is derived, particularly in the development of the auditory bulla, relative to more primitive, closely related species such as Merycoidodon culbertsoni, the latter of which is well known from the badlands of the western United States. The White Springs oreodont pertains to a. Although oreodonts are very common from classic Oligocene and early Miocene deposits in the western United States, this group is poorly represented from Florida. Exceptionally well-preserved partial skeletal remains representing a minimum of six individuals of an oreodont are described from the White Springs Local Fauna, Columbia County, northern Florida. ![]()
